Vitamin D linked to cognitive health in Parkinson's and Alzheimer's studies
Research suggests a potential link between vitamin D levels and cognitive health in patients with neurodegenerative conditions.
A 2013 observational study involving 286 Parkinson's patients found that higher blood levels of vitamin D were associated with better memory performance and fewer depressive symptoms. However, researchers note that these findings do not prove that supplementation can slow the progression of the disease.
In a separate study conducted by Emory University and published in Sleep Medicine, researchers examined 54 adults at high risk for Alzheimer's due to sleep and mild cognitive issues. The study found that participants taking at least 5,000 IU of vitamin D daily scored over 13% higher on the Montreal Cognitive Assessment (MoCA) compared to those not taking supplements. This effect was observed with both vitamin D2 and D3. Notably, doses below 5,000 IU did not show significant cognitive differences compared to non-users.
